vario PYRO cube

A reliable allrounder

Stable isotope laboratories have ever increasing demands for functionality and versatility. H and O isotopic determination in solids and liquids often requires pyrolysis at temperature of up to 1,500 °C. At the same time, laboratories need routine for carbon, nitrogen, and sulfur isotope ratio determination as well as elemental concentration analysis. In the past, laboratories have had to invest in two separate analyzers to cover this range of analysis; one for combustion and the other for pyrolysis.

The vario PYRO cube breaks new ground by combining an up to 1,500 °C pyrolysis analyzer with a fully functional elemental analyzer for carbon, nitrogen, and/or sulfur determination with separate combustion and reduction tubes.

Backflush technology for unbiased results

Oxygen isotope ratio determination of high nitrogen containing samples poses analytical challenges. The use of Elementar purge and trap technology results in complete baseline separation of the N2 from the CO peak and superior CO peak focussing. The system uses a special backflush system (patent applied for) to remove background bleed of the pyrolysis reactor from the CO peaks.

The vario PYRO cube is a member of Elementar's well renowned "cube family". The very small footprint is the result of the most advanced functional design in the market. Even the power supply for the 1,500 °C furnace is incorporated in the compact design of the vario PYRO cube with a footprint of only 42 x 55 cm.

Customer Spotlights

Here are a selection of our customers around the world that are using the vario PYRO cube in their research


Dr Federica Tamburini
Plant Nutrition Group, ETH Zurich, Switzerland

Dr Federica Tamburini is a researcher in the group of Plant Nutrition at the Institute of Agricultural Sciences at ETH Zurich (Switzerland), where she manages the stable isotope facility. The group uses the vario PYRO cube elemental analyzer for investigating the phosphorous cycle in soil/plant environments by analysing 18O in phosphate materials. 18O analysis of phosphate has previously been considered a demanding analysis but by using the vario PYRO cube, Dr Tamburini and colleagues now measure these sample types routinely. 


Dr Peter Wynn
Lancaster Environment Centre, Lancaster University, UK

Dr Peter Wynn is a Senior Lecturer at Lancaster University, and is based within the Lancaster Environment Centre (LEC). He is a Stable Isotope Geochemist researching in the fields of palaeoclimate reconstruction and glaciology. The department's particular specialty is analyzing sulfur isotopes and undertaking high temperature oxygen pyrolysis and the team has established techniques to extract sulfur isotopic signals from palaeo records, including speleothems, tree rings and carbonate rocks. Using the vario PYRO cube elemental analyzer, the group are able to determine the 34S and the 18O isotopic ratio of sulfate materials to help answer questions about deep geology and pollution migration.
